HOSE-CLAMP.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed October 20, 1906. Serial No. 339,805.

To all whom it may concern:

Be it known that 1, JOHN R. O ANo a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented new and useful Improvements in Hose-Clamps, of which the following is a specification.

My invention relates to improvements in hose-clam 3s, and consists in providing the perforate end ears with reinforcing side flanges, without increasing the width or thickness of the ends of the blank from which the clamp is formed; also'in giving a slight outward bend to the tip of the tongue to avoid cutting or injuring the material of the hose.

nIn clamps as heretofore made, the tip of the tongue (provided to span the space between the ears and prevent inching of the hose) rested in contact wit the hose, or waspressed against it, often cutting and abrading the rubber, or other softer material, of which the hose was made. Old clamps have also been provided with side flanges, .but they were made from special blanks having wider or heavier ends, which was troublesome and expensive, and in the finished clam the ends were as wide as the middle, there ore heavy and clumsy.

My invention is fully shown in the drawing herewith, in which the reference numerals of the description indicate the corre sponding parts in all the figures.

Figure l is an elevation of a hose-clamp. Figs. 2 and 3 are elevations of Fig. 1 respectively from the left and the right. Fig.

' 4 is a plan of a clamp, before being bent up,

. at the ends are bent in with e flanges formed at one end and with the op osite end left unfinished; Figs. 5 and 6 i lustrate a modified form of clamp in which the tongue is made as a separate piece. My hose-clamp is formed from a blank of steel, brass or other suitable metal of uniform width and thickness so that the blanks may be out, without waste, from the usual commercial bars, or. plates. The cars 1 are bent up'substanti ally at a right angle to the'body of the blank, and the side edges forming the reinforcing flanges 2 2 for said ears, so that the tips are narrower than the body of the clamp, asillustrated. Said ends are thus very strong to resist the strain of the clampin bolt 3, and also are neat, and give a good finish and lightness in appearance to the entire clamp. As shown m Fig. 3, the nut 4 fits between said flanges, which also afio'rd which assist in gripping the hose, and have auotherand important function. The metal from one of the slots (6) is entirely cut away, but for the opposite slot (7 is not so cut away at end 8 but is bent back inwardly in a loop 9, to form the tongue 10, Which spans the space between the ends of the c amp, when it is applied to the hose.- It will be understood that the tip '11 of said tongue, when forced against the softer hose under the opposite side of the clamp, tends to cut, or bite, into the hose, which is an objection long recognized, and'the subject of complaint by users, but not heretofore remedied in any way. so far as I know. It will be understood that in stamping these clamps in large quantities, often the tongues are sharp,

or provided with a bur which increases this danger. I'have overcome this disadvantage by forming the tongue end with a sli ht outward bend or curve, so that the tip does not come in contact with the hose and cannot be forced against it. It will be evident that such, a construction of tongue tip'is not practical with a solid hose clamp, but only where the slot 6, or corresponding opening, is made to receive such ontwardly bent tip. This apparently slight change has proved'very suc cessful and of great importance in practice.

Figs. 5 and 6 show a modified form of a clamp to which my invention may be applied. The tongue, or tongue piece, is formed separately as shown in Fig. 6, with a perforated, flat lug 19. bent up at an angle,

corresponding to the angle of the ears 13.

This tongue-piece is secured to the body of the clamp by the bolt 3, with the tongue extending inwardly through the slot on one side, to span the space between the clamp ends, and having its outwardly bent tip received in the opposite slot.

. My invention is particularly adapted to be applied to sheet metal clamps, but I do not wish to limit DIYSQlffhQI'Ql'OyUO]? to the form here shown. 1

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. As a new article of manufacture, a onepiece sheet metal hose clamp, having outwardly extending, substantially parallel end cars, perforated for the clampingbolt, longitudinal slots on the opposite sides of the clamp middle and extending adjacent to the ears, an integral tongue bent back and in wardly to span the space between the ears, said tongue having an outwardly curved tip adapted to lie in the opposite slot when the clamp is in position, and reinforcing side flanges for the ears and ends of the clam on both sides, said flanges being arrang inwardly of the edges of the body of the clamp to form narrow ends.

2. As a new article of manufacture, a sheet-metal hose clamp formed from a blank of uniform width and thickness, from end to end said clamp having perforated end ears outwardly bent and substantially parallel, and reinforcin side flanges for the ears, said flanges being ent inwardly from the side margin of the clamp, to form clam ends narrower than the body and to s an t e corner formed between the ears an the clamp body, substantially as described and shown. 3. A metal hose-clamp having outwardly extending ears at the ends of the body, means to clamp the ears together, and a tongue wardl y curved away from the hose.

4. A one-piece sheet metal hose-clamp having perforated ears at the ends of the clamp body, outwardl extending and substantially parallel, a c am'ping boltfitted to said ears and a nut fitted to said bolt, an integnal tongue attached at one end to the body and adapted to span the space between the body ends, said tongue having its free end outwardly bent away from the hose, and the clamp body having a free space to receive said bent end.
